Rugby match

Broked Rule

In the last rugby match on March 19 the player Jonah Lomu broked a rule, he was on the floor  and takled a guy, that is not acceptable because the rugby rules say that you can not tackle a player  if your knees are touching the ground. How I said before this is not acceptable.
I would like that the referee try to be more concentrated in the game, watch the players in the ground and had their eyes opened all the game.
Thanks and good bye.
